MANILA (AFP) – The Philippine Senate said yesterday it will conduct a formal probe of ex-president Rodrigo Duterte’s arrest and swift handover last week to the International Criminal Court (ICC), which is to try him for alleged crimes against humanity. The 79-year-old, the first Asian former head of state charged by the ICC, stands accused of the crime against humanity of murder over his years-long campaign against drug users and dealers that rights groups have said killed thousands. The probe was initiated by Senator Imee Marcos, sister of President Ferdinand Marcos but a close friend of Duterte’s eldest daughter, Vice President Sara Duterte. The two families have had a spectacular falling out since Marcos teamed with Duterte to win an election landslide in 2022. The latter has since been impeached on charges that include an alleged assassination plot against the president. “As chairperson of the Senate Committee on Foreign Relations, I am calling for an urgent investigation into the arrest of former President Rodrigo Roa Duterte, an issue that has deeply divided the nation,” Imee Marcos said in a statement yesterday.
